The Canadian

Paul Guilbault of Lavaltrie — From Fort Walla Walla to French Prairie, 1821–1849
A Quebec baptism record opens his story. A governor’s published travel journal names him three times in the mountains of New Caledonia in 1828. The Catholic Church Records of the Pacific Northwest document his marriage, six children, and his place at the center of the Fort Vancouver and French Prairie community — as husband, father, godfather, and witness — from 1831 until his death ca. 1849. He never returned to Quebec. He built an entirely different life, documented in an entirely different archive.

Baptismal register, St-Paul-de-Lavaltrie, January 1798 — the only Quebec parish record that names Paul Guilbault before his entry into HBC service

The Challenge

His Quebec record is a single entry: a baptism in January 1798. Every generation above him can be documented back to 1667. Every generation below him in the extended family left parish records in Quebec. Paul Guilbault himself did not.

Paul Guilbault was born January 21, 1798, in the parish of St-Paul-de-Lavaltrie (Joliette) and baptized the following day. His father was François-Régis Guilbault, a farmer from St-Paul-de-Joliette; his mother was Marie Archange Larivière. They had married at L’Assomption on February 7, 1786. The baptismal record is clear, well-preserved, and thoroughly documented in the PRDH. It is also, in the Quebec record system, the last thing Paul Guilbault ever appears in.

There is no Quebec marriage record. No Quebec death record. No occupation designation in a child’s baptism register — because no children appear in Quebec with him as father. No notarial act. No land transaction. No census appearance in the province. After January 22, 1798, the man who will spend nineteen years in HBC service and be named by a governor’s journal in the mountains of New Caledonia simply does not exist in the Quebec record system.

Five Generations Documented Above Him

The silence is not for want of records in the family. The five generations above Paul are thoroughly documented through PRDH, the Gauthier document, and the same record system that then falls silent on him:

1 Pierre Guilbault, de l’Aunis × Louise Sénécal — married October 6, 1667, Québec
2 Joseph Guilbault × Anne Pageau — married May 3, 1694, Charlesbourg
3 Charles Guilbault × Catherine-Antoinette Deguise Flamand — married March 19, 1727, Québec (Notre-Dame)
4 Charles Guilbault (b. 8 Jun 1727, d. 3 Dec 1764) × Marie Catherine Jourdain Bellerose — married June 8, 1750, Québec (Notre-Dame). PRDH #144133.
5 François Guilbault (b. 4 Sep 1760, L’Assomption; d. 28 Jul 1843, Joliette) × Marie Archange Larivière Rivière — married February 7, 1786, L’Assomption. PRDH #190780.
6 Paul Guilbault — born January 21, 1798; baptized January 22, 1798, St-Paul-de-Lavaltrie. ★ Last Quebec record.
The Family Context He Left Behind

Paul’s father François (b. 1760) and his uncle — the Guilbault family’s great voyageur Gabriel (b. 1762, son of Charles × Deguise Flamand’s son Gabriel b. 1731) — had shaped the family’s relationship to the fur trade. Gabriel’s NWC service brought him to Oka Mission, where he married Marie Josephte Abitakijikokwe in 1801. His brother Paul père (b. 1761), the “Invisible Voyageur” of the companion case study, had worked for the North West Company in the Athabasca Department in 1820–1821 — and then come home to St-Paul-de-Lavaltrie, converted his wages into grain annuities, and died a cultivateur in 1831. His children and grandchildren remained in Quebec.

Paul (b. 1798) entered HBC service the same year his older cousin’s NWC account was settled. He was twenty-three years old. He left in the same season the fur trade world was reconstituting itself after the 1821 merger. He never came back.

What Silence Cannot Answer Alone

The absence of Quebec records for Paul after 1798 is meaningful negative evidence — but it is not an explanation. Men who spent the full span of their working lives in the interior and never returned to Quebec are well-documented in the HBC record system. Their Quebec parishes simply closed the file with the baptism entry. The investigation must go where Paul went: west.

Peace River: A Canoe Voyage from Hudson’s Bay to Pacific, page 23 — the entry for September 14, 1828, naming Paul Guilbault as a Canadian on the McLeod Lake to Fort St. James portage in New Caledonia

The Breakthrough

Two sources break the silence. The Gauthier document establishes nineteen years of HBC service and a link to the Oregon community. The McDonald journal names him directly — three times, across nine days — leading a transport party through the mountains of New Caledonia in September 1828.
1. The Gauthier Document: HBC 1821–1840
Verdict: Service period and identity confirmed through secondary source with primary pedigree citations Secondary Raymonde Gauthier, Ph.D. (History, Laval University), “Ancestry of French Canadians to Oregon Prior to 1842” (2013, oregonpioneers.com), entry #57, identifies: GUILBAULT, Paul; HBC 1821–1840; born January 21, 1798, baptized next day in Lavaltrie; linked to Hilaire Guilbault. The document provides a five-generation pedigree chain with specific marriage dates and locations, each independently confirmable in the PRDH. The HBC service dates — 1821–1840 — represent nineteen years, the full span from the NWC–HBC merger to the close of the traditional voyageur era. The designation “linked to Hilaire Guilbault” connects him to a second family member documented in Oregon, addressed below.
2. The McDonald Journal: Named in New Caledonia, September 1828
Verdict: Named individual confirmed in New Caledonia; interior service and transport role established Published Primary Archibald McDonald, Chief Factor, Hudson’s Bay Company, kept the journal of Governor George Simpson’s 1828 canoe voyage from Hudson’s Bay to the Pacific. Published as Peace River: A Canoe Voyage from Hudson’s Bay to Pacific (Ottawa: J. Durie & Son, 1872). The journal records three separate entries naming Paul Guilbault, across nine days, on the portage between McLeod Lake (Trout Lake Post) and Fort St. James, Stuart’s Lake — in what is now north-central British Columbia, New Caledonia district.
September 14, 1828 — p. 23
“Met a Canadian [Paul Guilbault] and four Indians about five. Rode on another hour, and encamped at a small lake on our right, in what is called the Brulé. [Burnt wood district.] Guilbault and the Indians proceed to McLeod’s Lake for loads to-morrow morning.”
September 15, 1828 — p. 23
“Before we parted from Guilbault and followers this morning, we gave about 25 lbs. pemican to put into cache until their return, as their provisions from the Fort are not adequate to the journey.”
September 22, 1828 — p. 29
“Late last night, Guilbault, and the four carriers that accompanied him, arrived with their loads, as did also, in the course of this forenoon, the two that followed him on the 16th.”

Three things stand out in these entries. First, McDonald identifies Paul as “a Canadian” before naming him — the category designation that placed French-Canadian employees within the HBC’s carefully stratified workforce. Paul was recognized as a Canadian in the interior, not as an anonymous figure requiring introduction. Second, he was leading four Indigenous carriers independently, not traveling as part of a named officer’s party. This is the work of an experienced interior transport man operating on his own authority. Third, he completed the round trip: McLeod Lake to Fort St. James and back, through difficult mountain terrain, arriving with all loads delivered. He was thirty years old and seven years into his HBC service.

Governor Simpson’s party at the time included some of the most significant figures in Pacific Northwest history: James Douglas (later Governor of British Columbia), William Connolly (Chief Factor), Richard Hamlyn (surgeon), and Colin Fraser (Simpson’s piper, who played bagpipes to “the great astonishment of the natives” on the same portage Paul had just traversed). Paul Guilbault worked the same territory, the same season, in the same landscape — invisible to history because he was a carrier, not a gentleman, and the gentlemen wrote the journals.

3. The Hilaire Connection: Oregon in Sight
Verdict: Family link to Oregon community established through second cousin once removed; Paul’s western destination probable but not yet confirmed Probable Gauthier’s explicit linkage of Paul to Hilaire Guilbault is significant. Hilaire (b. June 23, 1818, Verchères; PRDH #2462814) is Paul’s second cousin once removed — both descend from Charles Guilbault × Catherine-Antoinette Deguise Flamand (married 1727), through the brothers Charles (b. 1727, Paul’s great-grandfather) and Gabriel (b. 1731, Hilaire’s great-great-grandfather). Hilaire served HBC 1838–1848 — overlapping Paul’s service period by two years — and is documented settling permanently in Oregon Territory: married Vancouver County April 21, 1842; provisional land grant Lewis County March 8, 1847 (Vol. 4, Pg. 205); died St. Paul, Marion County, June 24–26, 1849; buried Saint Paul Roman Catholic Mission Cemetery. His son François Gilbeau (b. 1847, d. November 8, 1851) is buried at the same cemetery. Gauthier’s document, which covers “Ancestry of French Canadians to Oregon Prior to 1842,” includes Paul precisely because he belongs to the same westward migration community.
Early Oregonians Database — Guilbeau, Paul: born ca 1800, died ca 1849, arrived 1833, married Walla Walla Catherine 1838 and Walla Walla Française 1848, provisional land grant Champoeg 1846

The Result

The Early Oregonians Database found him. The Catholic Church Records of the Pacific Northwest documented his marriage, his six children, his two Walla Walla wives, and his presence at the center of the Fort Vancouver and French Prairie community for nearly two decades. He did not disappear into the interior. He built a life — and that life is documented.
Arrived Oregon 1833 — Documented Through 1849

The Early Oregonians Database (Oregon State Archives) records Guilbeau, Paul: born ca. 1800, died ca. 1849, arrived Oregon 1833 — five years after the McDonald journal placed him on the McLeod Lake portage. He arrived at Fort Vancouver by 1831, when the Munnick annotation A-34 records he was sent from Fort Walla Walla to join John Work’s Snake Country brigade. A provisional land grant at Champoeg (Vol. 3, Pg. 079) was filed September 7, 1846. He did not live to patent the claim under the Donation Land Claim Act.

Marriage to Caty Walla Walla — December 29, 1838

Record M-18 in the Catholic Church Records of the Pacific Northwest (Vancouver Vol. I) documents Paul Guilbault’s marriage to Caty Sakaïan, Walla Walla by nation, on December 29, 1838, at Fort Vancouver. Paul was in service of the Honorable Company of Hudson’s Bay, domiciled at Fort Vancouver. Witnesses: James Douglas, Esquire, and William Fraser Tolmie, Esquire. Three pre-nuptial children were recognized as legitimate at the ceremony: François (aged 6, born ~1832), Louis (aged 2, born ~1836), and Paul (aged 7 months, born 1838). Caty Sakaïan was baptized the same day as B-213, the record immediately preceding the marriage entry in the same register.

Six Children Documented

The Catholic registers document six children of Paul and Caty across five years:

  • François — recognized at marriage, born ~1832; re-confirmed B-876, baptized January 29, 1843 at approximately 11 years, with godfather Hilaire Guilbeau and godmother Louise Walla Walla
  • Louis — recognized at marriage, born ~1836; B-46/47, baptized November 29, 1840, aged 5½ years
  • Paul — recognized at marriage, born 1838; B-46/47, baptized November 29, 1840, aged 2½ years
  • Marie — B-41, baptized June 20, 1841, born May 29; godfather Michel Cotnoir, godmother Mathilde Fagnant
  • François (B-876) — baptized January 29, 1843; godfather Hilaire Guilbeau; godmother Louise Walla Walla
  • A sixth child referenced in the Munnick A-34 annotation — not yet individually identified in the register record

Caty Walla Walla died in 1848. The Munnick annotation confirms six children total.

Hilaire and Paul — Cousins and Godparents

B-876 makes explicit what the Gauthier document implied with the phrase “linked to Hilaire Guilbault.” When Paul’s son François was baptized in January 1843, Hilaire Guilbeau stood as his godfather, with Hilaire’s own wife Louise Walla Walla as godmother. The two cousins once removed were not merely in the same Oregon community — they were godparents to each other’s children. The Early Oregonians Database records Hilaire’s own marriage to Louise Walla Walla in April 1842, with four of her children adopted at the same ceremony (M-2). These families were interwoven.

Paul as Community Figure

The Munnick index for Vancouver Vol. I lists Paul Guilbault on more than fifteen separate pages — as godfather, as witness at burials (S-3, S-4, S-8, S-9, S-11 in 1840–1841), and as present at baptisms across the Fort Vancouver community through 1843. He served as godfather to the child of Thomas Tawakon, Iroquois — a family he was apparently close enough to that after his first wife Caty died, he married Tawakon’s widow. He was a witness at the burial of Marie and Joseph, Cowlitz nation, in December 1840. He was godfather to Michel, child of the engagé Louis le frisé, in July 1839. The index is a map of a man embedded in his community.

Marriage to Françoise Cayuse — November 1848

After Caty’s death, Paul married Françoise Cayuse (also identified as Walla Walla by nation in the Early Oregonians Database) on November 5/6, 1848, in Marion County, Oregon. The Early Oregonians Database records Françoise (also called Louise; alias “—, Louise”) as born ca. 1810, with prior marriages to Thomas Tewatcon (Vancouver Co., July 8, 1839) and Paul Guilbeau. After Paul’s death she married Laurent Sauvé on April 9, 1850, and survived to the 1880 census in Wasco County. B-173 (July 4, 1839) also records Paul as godfather for Pierre Tawakon — son of Thomas Tawakon and Françoise Walla Walla — the year of her first marriage, confirming the long friendship the Munnick annotation describes.

Researcher’s Note

Paul Guilbault (b. 1798) is the first cousin once removed of Paul Guilbault père (b. 1761) and second cousin once removed of Gabriel Guilbault père (b. 1762) — the researcher’s 4th-great-grandfather — through the shared ancestor couple Charles Guilbault × Catherine-Antoinette Deguise Flamand (1727). The four men — Gabriel the voyageur who married Abitakijikokwe at Oka, the older Paul who came home to Quebec, this Paul who built a Walla Walla family in Oregon, and Hilaire who followed him west and died at St. Paul Mission — represent four branches of the same extended family navigating the same historical moment from four different directions. The Catholic Church Records of the Pacific Northwest, consulted in the same research period for a parallel project tracing the Nipissing and fur trade community of French Prairie, revealed Paul’s Oregon life entirely unexpectedly. The convergence of two separate research threads in the same archive is documented in the companion blog post.

Remaining Open Questions

The HBCA post journals for McLeod Lake (B.188 series) and Fort St. James have not yet been searched for Paul’s appearances in seasons beyond 1828 — his interior career between 1828 and his Oregon arrival in 1831 or 1833 is not yet documented. The sixth child referenced in Munnick A-34 has not yet been individually identified in the register record. Whether Paul died in the gold fields (as the annotation suggests) or elsewhere in Oregon remains unconfirmed. His pre-nuptial son François (born ~1832, before the 1838 Fort Vancouver marriage) was born during Paul’s Snake Country service — his mother has not yet been identified in any surviving record.
